Referring to FIG. 1 to FIG. 4, the combination frame material 1 providedby the present invention comprises an outer frame 10 and an inner frame20.

The outer frame 10 is made of plastic-wood material in strip shape. Theraw material of the outer frame 10 is an extrusion of a mixture mainlyof thermoplastic and natural fiber (such as wood powder, rice hull,wheat straw, and bamboo powder). The outer frame 10 has an outer sideand an inner side, while the inner side is provided with a wood-likepattern, and has two parallel combining grooves 11, 12 with a middlepillar 13 therebetween for dividing the two combining grooves 11, 12.The combining grooves 11, 12 are provided with a first inner wall 111,121 and a second inner wall 112, 122 oppositely disposed against thefirst inner wall 111, 121, respectively, while the first inner walls111, 121 and the second inner walls 112, 122 are provided with at leastan inclining concave strip 14, respectively. In the preferred embodimentof the present invention, the first inner wall 111, 121 has two concavestrips 14, respectively, and the second inner wall 112, 122 has oneconcave strip 14, respectively.

The combining grooves 11, 12 further have a bottom wall 113, 123,respectively, while two sides of the two bottom walls 113, 123 areprovided with a corner recess 15, respectively, which is in aconcave-arc shape, thereby preventing the outer frame 10 to deform whenexposed to heat. Furthermore, two sides of the outer frame 10 areprovided with a connect groove 16, respectively, while a connector 17(as shown in FIG. 5) is received in the connect groove 16, so as toconnect another outer frame 10. The second inner walls 112, 122 of thecombining groove 11, 12 are oppositely disposed at the two outer facesof the middle pillar 13, respectively.

The inner frame 20 is made of an aluminum extrusion strip, having twoparallel combining parts 21, 22 for being received in the two combininggrooves 11, 12. A pillar groove 23 is disposed between the two combiningparts 21, 22 for receiving the middle pillar 13. Therein, the combiningparts 21, 22 are provided with a first outer wall 211, 221 and anopposite second outer wall 212, 222, respectively. The first outer wall211, 221 are provided with at least one convex strip 24, respectively,for matching the concave strip 14. In the preferred embodiment of thepresent invention, each of the first outer walls 211, 221 has two convexstrips 24.

Furthermore, the first outer wall 211, 221 and the second outer wall212, 222 are connected by a combining wall 213, 223, respectively, suchthat the combining wall 213, 223, the first outer wall 211, 221, and thesecond outer wall 212, 222 of the inner frame 20 form a U-shapedstructure. When the inner frame 20 is combined with the outer frame 10,the combining wall 213, 223 contact the bottom walls 113, 123,respectively, whereby the inner frame 20 and the outer frame 10 arecombined with each other in an identical direction. In other words, theopenings of the inner frame 20 and the outer frame 10 face the samedirection, facilitating the combining process of the inner frame 20 andthe outer frame 10.

Also, a slope 25 is disposed at the junctions of the combining wall 213,223 connected with the first outer wall 211, 221 and with the secondouter wall 212, 222, respectively, for correspondingly overlapping thecorner recess 15. The second wall 212, 222 of the combining part 21, 22is oppositely formed at the two inner faces of the pillar groove 23,respectively.

Referring to FIG. 4, during the combination, the inner frame 20 isallowed to be fixed on the floors, walls, or other locations in advanceby use of fasteners (not shown in the drawings), with the combiningparts 21, 22 thereof facing outward. Next, the outer frame 10, with thecombining grooves 11, 12 respectively facing the combining parts 21, 22,is tapped inward to couple the inner frame 20, so that the match of theconvex strips 24 and the concave strips 14 prevents the inner frame 20and the outer frame 10 from departing from each other. Also, due to theopenings of the inner frame 20 and the outer frame 10 facing the samedirection, the inner frame 20 and the outer frame 10 are able to becombined efficiently, so as to prevent aligning difficulty thereof. Inaddition, the slope 25 provides the convenience of the outer frame 10smoothly coupling the inner frame 20, so that the outer frame 10 isallowed to efficiently coupling the inner frame 20 even if the innerframe 20 is in an expanding status. Also, the middle pillar 13 betweenthe combining groove 11 and the combining groove 12 is received in thepillar groove 23, whereby the combining walls 213, 223 contact thebottom wall 113, 123, respectively. As a result, when the outer frame 10bears an external force, the middle pillar 13 is able to disperse theexternal force for achieving a better support effort, so that the outerframe 10 is prevented from deform due to force bearing, thus providing ahigher structural strength to the combination frame material 1 of thepresent invention.

Furthermore, even if the two combining parts 21, 22 of the inner frame20 deform to be narrowed, the two slopes 25 thereof are able to pushtoward the middle pillar 13, whereby the pillar groove 23 clamps themiddle pillar 13 with higher tightness. The concave strips 14 on the twosides of the middle pillar 13 allow the outer frame 10 to be partiallycoupled and engaged, so as to provide a buffering effect, therebymitigating the deformation of the outer frame 10 and realize a higherstructural strength of the product.

With the foregoing configuration, the inner frame 20 is able to be fixedat a predetermined position in advance. The outer frame 10 is providedwith a wood-like pattern to achieve an appearance variety, and at thesame time to solve the disadvantages of a real wood material consumingnatural resource and of a metal material being aesthetically stiff andheat absorbing easily.

Referring to FIG. 5, with the foregoing configuration, the combinationframe material 1 in accordance with the present invention is allowed tobe applied on floors.

Referring to FIG. 6, with the foregoing configuration, the combinationframe material 1 in accordance with the present invention is allowed tobe applied on walls.

Referring to FIG. 7, with the foregoing configuration, two combinationframe materials 1 in accordance with the present invention are allowedto be combined back to back by use of the two inner frames 20 thereof,with the two outer frames 10 thereof are combined to the two innerframes 20 afterward, respectively, so as to form a column 2.

With the description above, the combination frame material provided bythe present invention is allowed to be applied on scopes of floors,walls, or columns. The outer frame and the inner frame models arepossible to be molded for lowering cost of manufacturing. Furthermore,when the outer frame and the inner frame are being combined, the tworespective openings face the same direction, such that the combinationbetween the two frames is accelerated, thus facilitating theconstructional decoration. Therefore, the combination frame material ofthe present invention is applicable in various scopes.
